:SPECIPICATION forming part of Letters Patent No. 378,693, dated-February 28, 1888.

. Application filed September 17, 1887. Serial No. 249,915. (No model.)

To all 2071,0122. it may concern.-

' be collapsed or reduced in size, so as to occupy little storage-room and to enable the machine to pass through narrow doors or passages.

The invention consists of the improvements which will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, consisting of two sheets, Figure 1 is a side elevation of my improved tricycle. Fig. 2 is a top plan view thereof with the saddle removed. Fig.

l 3 is a vertical section of the steering-head and connecting parts on an enlarged scale. Fig. 4 is a vertical section of the upper portion of the steering-post, showing the manner of attaching the handle-bars thereto. Fig. 5 is a horizontal section in line a". m, Fig. 4. Fig. 6 is a fragmentary sectional elevation of the axle of the steering-wheels and the couplingsleeve connecting the inner ends thereof. Figs. 7, 8, and 9 are cross-sections in lines 00 x, 3/ y, and z 2, Fig. 6 respectively. Fig. 10 is a sectional elevation showing my improved steering-gear applied to a tricycle having a single steering-wheel and two driving-wheels. Fig. 11 is a modified construction of the coupling connecting the inner ends of the axle and the steering-wheels.

Like letters of reference refer to like parts in the several figures.

A represents the driving-wheel, and A A the steering-wheels, arranged in front of the same.

a represents the hub of the rear wheel,upon which is mounted a sprocket-wheel, c,- and b is the crank-shaft,arranged in front of the rear wheehand which is provided with a sprocketwheel, b, the sproeketwheels a and 5 being connected by an endless chain, b.

b represents the crank-arms, secured to the crank-shaft, and to which the pedals are attached. The main frame,in which the-drivingwheel is mounted, consists of an upper fork, B, a lower fork, B, an upright front tube, 0, and a steering-head, D. The branches of the forks are secured together with their rear ends on the same side of the driving-wheel and carry the hub a on a stationary axle in the usual manner. The upper fork, B, is secured with its front end to the upper end of the tube 0. The lower fork, B, is secured with its front end to the lower end of the steeringhead. The steering-head D is arranged in front of the drivingwheel A and secured with its upper end to the lower end of the tube 0 by means of a collar, d, formed on a lateral extension of the steering-head.

D is the spindle, arranged in the steeringhead and provided with a neck, D, extending forwardly therefrom. The steeringhead and the spindle D are slightly inclined forwardly, as clearly shown in Fig. 3, to cause the rear wheel to cant or incline inwardly in turning, thereby lessening the danger of upsetting the machine. The steering-l1eadD is provided at its upper end with a conical seat, d, for the upper spindle-center and at its lower end with an adjustable nut, d, which is provided with a conical seat, d for the lower spindlecenter.

E represents a reach extending forwardly from the neck D of the spindle D to the axle of the steering-wheels A A F represents the upright steering-post,turning in the tube 0 and provided at its lower end with a gear-segment, f,which meshes with an internal gear-segment,f, formed on the upper side of the spindle or neck D as clearly shown-in Fig. 3, so that by turning the steering-post F the reach E,with the front axle and steering-wheels A A",will be swung in one or the other direction. The gear-segment f, secured to the steering-post F, is made of somewhat smaller radius than the segmeut f, so as to give the rider the necessary leverage to render the steering easy.

G represents a short tube arranged in the upper end of the tube 0 on the steering-post F for supporting the saddle. The tube G is secured in the tube 0 by means of the front portion of the upper fork, B, which is provided at its front end with a split collar, 9, surrounding the upper end of the tube 0 and having a clamping-bolt, 9, whereby the split collar is firmly secured to the tube. The upper end of the outer tube, 0, is split longitudinally, as shown in Fig. 3, to enable the collarg to clamp the inner tube, G. This construction enables the tube G to be adjusted in the tube 0, so as to raise and lower the saddle.

H represents a bar or frame secured to the upper end of the tube G- and extending upwardly and backwardly therefrom. The frame 4H forms a support for the saddle H, which latter is provided with a spring, 72 which is adj ustably secured to the frame H in any suitable manner. The steering-post F turns freely in the inner tube, G, and extends with its up per end through an opening, h, formed in the upper portion of the saddle-supporting frame H.

I represents the handle-bars, adj ustably secured to the steering-post above the tube G and extending backwardly, outwardly, and upwardly on opposite sides of the saddle, as shown in Fig. 1. This construction ofthe handle-bars leaves the front of the machine entirely open and unobstructed between the steering-wheels, which enables the rider to dis mount easily and quickly when required, and it also relieves the hands of the rider from the vibration which is received when the handlebars are attached directly to the steering-head. The inner ends of the handle-bars are provided with concave recesses or seats 2', which rest against opposite sides of the steeringpost, and are hinged by an upright bolt, j, in front of the steering-post to a vertically-adjustable block, J, attached to the steering-post above the tube G. The block J is provided on its rear side with a dovetail tenon or feather, j, which enters a longitudinal dovetail groove, j", formed in the front side of the steeringpost F.

represents a clampingbolt which passes through horizontal openings 70, formed in the handle-bars in rear of the steeringpost F, and whereby the handle-bars are firmly secured to the steering-post. Upon loosening the bolt 7a the block J and the handle-bars can be raised and lowered on the steering-post.

The above-described arrangement of the saddle and handle-bars permits a slight independent adjustment of the saddle and handle-bars; but when a considerable movement of either is required it is necessary to adjust both the saddle and handlebars. v Y

The herein-described steering mechanism is equally applicable to and desirable for tricycles having two rear driving-wheels and a front steering-wheel, as shown in Fig. 10.

The axle of the steering-wheels A A is conr posed of two tubular sections, L L, which are secured at their outer ends to the steeringwheels and connected at their inner ends by a coupling or socket, M.. As shown in Fig. 1, the inner end of the section. L is arranged above the inner end of the section L, and the coupling M is provided with two transverse openings, m m, arranged one above the other and receiving the inner ends of the two sections. The outer end of the section L is bent forwardly and downwardly tothe hub of the right-hand steeringwheel, A, and the outer end of the section L is bent forwardly and upwardly to the hub of the left-hand steeringwheel, A as shown in Figs. 1 and 2. The inner ends of the sections L L are arranged loosely in the openings of the coupling M and are provided with spiral grooves a n, which extend from the inner ends of said sections to within a short distance of the bent portions thereof.

0 0 represent two studs or pins secured to the coupling M, and projecting with their inner ends, respectively, into the grooves n n of the sections L L.

The weight of the machine and rider tends to hold the studs 0 0 in the inner ends of the grooves 11. n, and thus retains the steeringwheels in their proper extended position. When it is desired to fold or collapse the machine, the front end of the machine is raised. The weight of the wheels, acting upon the bent outer ends of the axle-sccti0ns L L, causes the wheels to descend and turns the axle sections in the coupling M. This movement of the axle-sections causes the studs 0 0 to bear against the sides of the spiral grooves 02- n, whereby the axle-sections and the wheels A A are drawn inwardly until the axle-sections have been turned about a quarter-turn. The

front end of the machine is then lowered, so as to permit the weight of the machine to rest on the wheels, and a slight forward movement is given to the machine, which causes the axlesections L L to be drawn inwardly still farther by the studs 0 0 and spiral grooves n 12 until the axle-sections and wheels assume the position represented in Fig. 2, in which position the studs 0 0 rest against the outer ends of the grooves 11. n. In this manner the machine is readily reduced in width and length without the use of tools or loosening any of its parts. This permits the machine to pass through narrow passages or doors and to be stored in a small space.

If desired, the machine may be used in this position as a narrow-gage machine.

If it is desired to store the machine in the smallest possible space, the handle-bars are folded forwardly, as represented by dotted lines in Fig. 2, by'removing the clamping-bolt k and swinging the handle-bars upon the vertical bolt j as a pivot.

If desired, the spiral grooves 12. n and pins 0 o of the axle-sections may-be omitted and the latter be secured in the coupling M by means of setscrews p, as shown in Fig. 11, in which case the wheels are pressed together after loosening the set-screws. This construction is less expensive than that first described, but is not so convenient.

I claim as my invention- 1. The combination, with the steering-head and. the spindle provided with a gear-segment, of a steering-post centered above and between the spindle and its gear-segment and.
